Abstract

The present invention relates to a process for the preparation of astaxanthin having the formula <CHEM> comprising the step of oxidizing a dienolether, a dienamine, or a dienolate anion of canthaxanthin with an oxaziridine oxidant to produce an astaxanthin dihemiaminal, and then decomposing the dihemiaminal to produce astaxanthin. The process advantageously involves two less steps than the best known prior art process for the preparation of astaxanthin. The invention also relates to important intermediates in the preparation of astaxanthin, which is itself an important additive in the fish industry, the most important of which intermediates is the astaxanthin dihemiaminal.
